Notable and persistent and extraordinarily petty is their refusal to read AGENTS.md files, forcing the inclusion of their branding into the source of repos directly.
to be clear, I don't mean that Claude refuses to read AGENTS.md files, but that Anthropic refuses to bake AGENTS.md into the harness as a first-class feature.
Claude the model by now has learned what an AGENTS file is, and itself is not petty enough to ignore it for partisan purposes, but claude-code the harness doesn't natively support it.
